In OpenGL 2.x for Embedded System, a lot of basic scene/draw functions have been removed. It means that everything is made using vertex and fragment shaders. I have also added a gstglwindow backend for winCE that uses EGL (Native Platform Graphics Intercace) (which is a full part of OpenGL ES specification). It remove the use of wgl/glx functions.
